Usage

• Use SHOW_IF: condition to conditionally hide/show questions
• Place below a question or after question options to apply to that question
• Can also be placed after blocks, pages, or individual question options
• Supports operators: ==, !=, >, <, >=, <=, AND, OR, NOT
• For complex multi-line conditions, use triple-quote delimiters: SHOW_IF: """ ... """

Operator Precedence and Values

• NOT binds tighter than AND, and AND binds tighter than OR: a AND b OR c means (a AND b) OR c
• Use parentheses to group: (age >= 65 OR age < 30) AND consent == Yes
• Keywords are recognized in UPPERCASE only, so unquoted answer values containing words like "or" stay plain text: usage == Several weeks or more
• Values may be quoted: usage == "Several weeks or more"
• Malformed conditions are rejected when the survey is loaded, with an error naming the block, page, section, question, or option they belong to

Quoting Values

Quote a value whenever it contains an operator character (+, -, *, /, >, <, =) or an UPPERCASE keyword (AND, OR, NOT, IS, IS_NOT, ...). Otherwise the parser applies it as an operator instead of treating it as part of the text.

Plain text needs no quotes:

• usage == Several weeks or more
• status == Employed

A value containing an operator does:

• code == "A+B" — not code == A+B
• status == "Yes AND No" — not status == Yes AND No
• plan == "Level > Basic" — not plan == Level > Basic

Example

Q: Do you have pets?
- Yes
- No
VARIABLE: has_pets

Q: What kind of pet?
- Dog
- Cat
- Bird
- Other
SHOW_IF: has_pets == Yes

Usage

• - SHOW_IF: is placed as a sub-item under the option it controls
• The option is hidden when the condition is false
• Works with multiple choice, checkbox, matrix, and breakdown questions
• Uses the same condition syntax as question-level SHOW_IF:

Example

Q: Are you a business customer?
- Yes
- No
VARIABLE: business

Q: What type of account do you need?
- Personal
- Business
  - SHOW_IF: business == Yes
- Enterprise
  - SHOW_IF: business == Yes

Usage

• Use {{IF condition THEN text ELSE text}} syntax for conditional text
• Inserts conditional text within question text or page text
• Dynamically changes question wording based on previous responses
• ELSE part is optional

Example

Q: Are you a student?
- Yes
- No
VARIABLE: student

Q: {{IF student == Yes THEN What is your major? ELSE What is your occupation?}}
TEXT

Usage

• Use STARTS_WITH prefix == value to test multiple variables with a common prefix
• Tests if ANY variable starting with the prefix meets the condition
• Uses OR logic: true if at least one matching variable satisfies the condition
• Example: STARTS_WITH fraud == Yes checks all variables starting with "fraud"
• Useful for grouped questions with common variable naming patterns

Example

Q: Did you witness fraud?
- Yes
- No
VARIABLE: crime_fraud

Q: Did you witness theft?
- Yes
- No
VARIABLE: crime_theft

# **Follow-up**
